Dean Weymes will have £10,000 deposited into his account every month for 30 years

Dean Weymes, a native of Dublin, is “set for life” after winning a UK lottery prize that grants him £10,000 ($12,140) a month for the next 30 years.

The Irish man is looking forward to pursuing screenwriting, as well as caring for his family, and in particular, his autistic younger brother.

BBC reports that 24-year-old Weymes, who now lives in the UK with his sister, won the big prize on July 29. It was his first time playing the UK National Lottery’s ‘Set for Life’ game when his Lucky Dip ticket matched five main numbers and one Life Ball.

He is the fourth winner of the jackpot prize that was only launched in March and is the first winner to go public. His prize is set to amount to £3.6 million ($4.3 million) by the time he’s 54.

Weymes said: "Getting £10,000 every month allows me to start working through my bucket list.”

"I have always wanted to fulfill my dream to become a scriptwriter and this now allows me the freedom to do it. I studied screenwriting at university as this has always been a passion of mine but I have never been able to do anything with this.”

"I can turn my passion into a job - something I never thought I could do."

He added: “I cannot actually believe that I am really going to be able to do these things – and do them right now. Everything still seems quite unreal – the news really is still sinking in.”

While Weymes has already put a down payment on a new house and is working on organizing a family trip to Disneyland, he is also looking forward to helping provide care for his 23-year-old autistic brother.

In 2015, Weymes produced this touching video about his brother:

Weymes now tells The Mirror: “I feel a ­responsibility to ­guarantee his care for the future.”

"My brother is basically like a baby, he’s non-verbal but can say our names and some other things. He can grab hold of you and it’s very difficult because he has unbelievable strength.”

“My parents are getting older so it’s harder for them to care for him.”

“I want him to have the best-trained carers and I want my parents to have regular hours in the day where they can have a break.”
